To all whomV itl-may concern:

Be it known that I, FRANCIS STICKER, o New York, in the county of New York and State of New York, have invented certain new and usefullmprovements in Steam-Injectors and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.-

The object of this invention is to provide a steam-injector designed especially for motor-vehicles. It is well known that great difficulty is experienced in supplying the boilers of motor-vehicles with water while such vehicles are in operation and that owing to the speed at which they travel and the necessity for employing light-weight machinery the ordinary injectors, even ot' the smallest type heretofore known, are not adapted for such service, for, aside' from their weight, it isimpossible to prevent breakage of the jet or column if the injector is brought into operation while the machine or vehicle is in motion.

By my invention I provide au Ainjector of very lightweight, occupying but little space, but capable of supplying boilers with water without danger of any break occurring in the jet or column of Water no matter at what speed the vehicle may be traveling.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a verticaly longitudinal sectional View. Fig. 2 is a slightly-enlarged cross-sectional view online 2 2, Fig. 1. Fig. 3 is a similar view on line 3 3, Fig. 1, looking in the direction of the delivery end of the injector.

Referring to the drawings, 1 designates the casing, having at one side the water-inlet opening 2, at its under side the steam-inlet opening 3 and boiler-outlet 4, while at its extreme end is the overflow-outlet 5. Extending through the steam-chamber 6 is a double steam-tube r7-that is, from the central open or lantern-like portion of this tubular body extend the steam-tube 8 of the lifter and the steam-tube 9 of the forcer, the former extending rearward and the latter forward in axial line with each other. In line with the lifter steam-tube Sis the'cornbining-tube 10, which empties into the discharge-chamber 12 of the lifter, which chamber is connected by an upper longitudinal channel 13, extending throughout the length ofthe casing, with the transverse opening wherein fits the controlling-cock 14, preferably of the type employed in the injectors known to the trade as the IEaISy-H The steam-tube 9 of the forcer opens into the water-chamber 15 of the forcer, which chamber derives it supply from channel 13. In line with this steam-tube is the combining and delivery tube 16 of the forcer, which tube has an overflow spill-slot 17, throughwhich the initial overflow passes into overflow-cham ber 18. Y The tube 16 opens into the dischargechamber 19, which connects with both the boiler-outlet and the opening wherein cock 14 is located. .This cock has three ports, registering, respectively, with the channel 13, the overiiow-chamber 18, and the dischargechamber 19. These ports are, as usual, relatively arranged, so that in turning the cock the initial overllow from channel 13 will be iirst cut olf, then the overflow from chamber 1S, and then the outlet from chamber 19,

.whereupon the established jet or column of water will pass to the boiler through the outlet 14.

For the purpose of regulating the quantity of water to be fed to the lboiler--that is, to control the workin g of the in jector.-I provide a throttle in the form of a tapered needle-like rod 20, secured to a screw-rod 21. By turning the latter the rod 20 will be extended into the combining-tube of the lifter, and thereby regulate the volume of water discharged therefrom. The extent to which the water is throttled is controlled by the extent to which the tapered rod is projected into the combining-tube.

In practice the steam entering' the steamchamber and passing through the open portion of the tubular body 7 will enter the two steam-tubes, that passing through thelifter steam-tube finding its way to the atmosphere through channel 13, while that passing through theforcer steam-tube will reach the atmosphere either through the same channel or through chambers 18 and 19, or all of them.

IOO

The steam upon reaching the atmosphere will effect the lifting of the Water into the Waterchamber of the lifter, which water passing through the lifter combining-tube will travel through channel 13. When the columnis established, all overflow is cut off by the turning of cock 14, and such column will thereupon pass to the boiler through the outlet 4.

An injector constructed in accordance with my invention is of but minimum weight, and the tubes of the lifter and forcer being in the same axial line and having a common source of steam-supply occupy but little space, and hence the size of the injector is made to fill the requirements insisted upon in motor-Vehicle construction. The injector is capable of easy manipulation and will supply Water to a boiler Without any break in the jet or column regardless of the speed at which the vehicle may travel. Once the steam is admitted the working of the injector depends merely upon the turning of the cock, While the quantity of Water discharged may be regulated by the turningr of the throttle.

I claim as my invention* l. A steam-injectorhaving the tubes of the lifter and forcer arranged in the same axial line for handling the steam and Water in opposite directions, and a passage-way between the discharge-chamber of the lifter and the water-chamber of the forcer, as set forth.

2. A steam-injector having the tubes of the lifter and forcer arranged in the same axial line, the steam-chamber being common to the steam-tubes of both the lifter and forcer, and a passage-way between the discharge-chamber of the lifter and the water-chamber of the forcer, as set forth.

3. Asteam-injectorhavingthe steam-tubes of the lifter and forcer in axial line with each other and y leading from a common steamchamber, the combining-tube of the forcer leading from the Water-chamber, and a passage Way connecting the lifter dischargechamber With the forcer Water-chamber, and thecombining and delivery tube of the forcer in line with its steam-tube, as set forth.

4. The casing having at one end a lifter dis- Ghargechamber, at or near the other end an overflow-opening, a channel or passage-Way connecting such chamber with such opening,

the forcer Water-chamber being supplied from said channel, the tubes of the lifter and the tubes of the forcer, the former discharging into said discharge-chamber-and the latter handling the Water from the Water-chamber of the forcer, and means for cutting olf the overliow, substantially as set forth.

5. The combination with the casing having a steam-chamber, a discharge-chamber at one end, an overow-opening at the other end, and a channel or passageway connecting said discharge-chamber with said opening, of the tubes of the lifter and forcer, arranged in axial line With each other, the two steamtubes leading in opposite directions from said steam-chamber, the Water-chamber of the forcer being open to said channel, and means for closing the overflow, substantially as set forth.

6. A steam-injector having liftei-tubes and forcer-tubes, and means for regulating the discharge of the lifter, Such means controlling the outlet of the combining-tube thereof, ,as set forth.

7. Asteam-injector having lifter-tubes and forcer-tubes, and means for regulating the discharge of the lifter, such means comprising athrottling-rod extended into the com bin ing-tube of the lifter, as set forth.

S. A steam-injector having the tubes of the lifter and the tubes of the forcer arranged in the same axial line forhandling the steam and water in opposite directions, and a throttlingrod extended into the combining-tube of the lifter for regulating the discharge of the latter, as set forth.

9. A steam-injector having the tubes of the lifter and forcer arranged in the same axial line forhandling the steam and water in oppositedirections, a passage-way between the discharge-chamber of the lifter and the forcer Water-chamber, and a throttle-rod extended into the combining-tube of the lifter, as and for the purpose stated. y

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
